To all whom it may concern:

'Be it known that I, GEORGE H. TRULOCK, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have inventednew and useful Improvements in Advertising Devices, of which the following is a specification.

My invention relates to advertislng devices and consists of the novel features herein shown, described and claimed.

My object is to make a plurality of advertising signs for mounting in a street car or the like and provide means whereby the signs travel continuously and apparently in a straight line.

Figure 1 is a sectional elevation of an advertising device embodying the principles of my invention, the view being taken approximately on the line 11 of Fig. 2 and looking in the direction indicated by the arrows.

Fig. 2 is horizontal sectional detail on the line 22 of Fig. 1 and looking downwardly as indicated by the arrows.

Fig. 3 is a vertical cross section substantially on the line 3-3 of Fig. 1 and looking in the direction indicated by the arrows.

Fig. 4 is an enlarged fragmentary sectional detail on a plane parallel with Fig. 2 and showing the shiftingspring, the view being taken on the line 44 of Fig. 5 and looking in the direction indicated by the arrows.

Fig. 5 is a fragmentary cross section on the line 55 of Fig. 4 and looking in the direction indicated by the arrows.

Fig. 6 is a fragmentary horizontal sectional detail upon an enlarged scale and on a plane parallel with Fig. 2 and on the lines 6-6 of Fig. 3 and looking downwardly and showing the driving mechanism.

Fig. 7 is an enlarged verticalcross section on the lines 77 .of Figs. 2 and 6 and looking in the direction indicated by the arrows.

Fig. 8 is a fragmentary side elevation looking in the direction indicated by the arrow 8 in Fig. 7, parts being broken away to show the details.

Fig. 9 is a fragmentary cross section as on the lines 99 of Figs. 1 and 2.

The bottom 1 is fiat and straight, comparatively narrow and of considerable length. The back wall 2 extends upwardly from therear edge of the bottom 1 and is of considerable height. The end walls 3 and 4 are rigidly secured to the ends of the bottom 1 and the back 2. The top wall 5 is hingedly secured to the upper edge of the back 2 and the tops of the ends 3 and 4. The frontwall 6 is only a narrow strip extending upwardly from the bottom 1 and connected to the ends 3 and 4.

The motor housing 7 extends downwardly from the bottom 1. The motor 8 is mounted in the motor housing 7 and has a worm 9 on the outer end of the motor shaft 10, meshing with a worm gear 11 fixed upon the lower end of the operating shaft 12. The operating shaft 12 is mounted vertically and extends through the bottom 1 and has a driving gear 13 fixed upon its upper end just above the bottom and below the upper edge of the front wall 6.

The box thus constructed is adapted to expose advertising panels 14, 15, 16 and 17 in a row, and the operating gear 13 is mounted in a plane between the advertising panels 16 and 17. A second operating gear 18 is mountedin a plane between the advertisingpanels 14 and 15. A track 19 is constructed upon the bottom 1 just inside of the front wall 6, and a similar track 20 is constructed upon the bottom 1 just inside of the back wall 2, said tracks, 19 and 20extendingfrom the operating gear 13 to the operating gear 18 in planes at the sides of the gear. 7 The panels 14', 15,16 and 17 are substantially alike, and when the panels 14, 15, 16 and 17 are in a line, as in Fig. 1 there are two other panels 21 and. 22

back of the panels 15 and 16. 7

Each panel 14, 15, 16, 17,21 and22 consist of a base 23, a gear rack 24, a runner 25, side frames 26 and 27 extending upwardly from the ends of the base 23. and a runner 28 connecting the upper ends of the side frames. The runners 25 operate in the tracks 19 and 20, and the runners 28 operate in similaitracks constructed below the top 5.

The gear racks 24 have semicircular ends and straight sides 30 and 31, the ends and sides being toothed to mesh with the operating gears 13 and 18. Plates 32 are secured to the side frames 26 and 27. Strips 33 are secured to the ends of the plates 32 and form recesses 34 to receive the end edges of the advertising cards.

Assuming that the advertising cards are to travel to the left, as indicated by the arrows 35, then the gear racks will mesh with the operating gear 13 and the panels will pass in front of the operating gear-'18 along the track 19, and as one panel passes out of mesh another will pass into mesh and push the first panel along and as the second panel passes out of mesh with the operating gear 13 a third panel will come into mesh with the operating gear 13 and push the first panel into mesh with the operating gear 18 and so on, the object being to make a continuous circulation of the six panels with four panels in View all the time.

1 he boards 36 and 37 are mounted inside of the end walls 3 and 4 to form spring seats. Bolts 38' and 39 are inserted through the end Walls 3' and 4. Clamping nuts 40" and 41 are screwed upon the bolts against the inner faces of the end walls. Adjusting nuts 42 and 43 are screwed upon the bolts and the boards 36 and 37 are placed upon the bolts against the nuts 42 and 43, so that the boards may be adjusted back and forth relative to the end walls 3 and 4 by manipulating the nuts 42 and 43' to the top when the top is'open and through the openings 44 and 45 in the bottom 1.

Sprin s 46 and 47 are placed upon the bolts 38 and 39" against the boards 36 and 37, and the spring boards 48 and 49 are placed against the springs 46' and 47. Guide plates 50 and 51 are fixed to the inner face of the board 48 and extend outwardly against the inner faces of the walls 2 and 6, and similar guide plates 52' and 53 are fixed against the inner face of the spring board 49 and extend outwardly against the inner faces of the Walls 2 and 6. Bowed leaf springs 54 and 55 are secured against the inneriaces of the walls 2 and 6'- near the gear 18, and similar bowed leaf springs 56 and 57 are secured to the inner faces of the Wall s 2 and 6 near the gear 13.

hen a panel passes the gear 18 it will engage the spring 55 and the spring 55 will 7 guide the freeedge of the panel toward the center of the spring board 48 and this movement wil l be insured by the guide plate 51. The panel will: press against the spring board 48 before running out of mesh with the gear 18, the spring 55 will hold the semicircu lar end 29 of the gear rack 24 against the gear 18' and cause the end 29' to travel past the gear to the opposite side opposite direction.

against the spring 54, and the tension of the spring board 48 will start the panel gear rack to mesh the teeth 30 or 31 with the gear 18 and cause the panel to move in the In the same way the panels are transferred from the back to the front by the springs 56 and 57 and the spring board 49.

In the practical operation when the parts are properly placed and adjusted and the motor 8 started the panels will travel continuously as long as the motor runs.

Various changesmay be made without departing from the spirit of my invention as claimed.

1 claim:

1. An advertising device comprising, in combination with a housing having an open front and having a front-track and a rear track and operating gears between the tracks; panels mounted ,to run upon the tracks having racks to mesh with the gears; means for operating the gears to move the panels one way on the front track; a slidably mounted partition fitting the ends of the housing adapted to engage the outer ends of the panels and having extending sidemembers adapted to guide the panel; and springs positioned behind the partition whereby the end tooth of the rack onjthe panel willbe kept in engagement with the gear while-passing the panel from one'track to the other.

2. An advertising device comprising a suitable housing having an open front and having a front track and a rear track and g gears adjacent tothe ends of and between the tracks; panels mounted to run upon the trackshaving racks to mesh with the gears; a slidably mounted partition fitoperatin ting the ends of the housing adapted to env gage the outer ends of the panels and having extending side members adapted to guide the panel; a second partition positioned outwardly from the first retractile springs mounted between the partitions; and means for adjusting the second partition relative to its distance from the gear.

In testimony whereof I have signed my name to this specification.

GEORGE H. TRULOCK.
